It's interesting how the propaganda story about "intercepted" Kinzhals is being spread together with the official US confirmation of "minor" damage to the Patriot system. Also we have videos which show explosions happening on the ground level (https://www.bitchute.com/video/paRpPOE15Gx4/ 0:33 and 0:42). Even if you believe in the debris story, it means that a rocket got in the range of ~100 meters of the system, which is already can be read as an interception failure for a Patriot-like system.
Of course, the Russian story of "destroying" the Patriot battery is also clearly exaggerated. It's quite probable that the most visible and easily targeted radar module got destroyed, while the rest of the system is fully intact or got hit lightly by debris.
If you destroy a ballistic missile, the debris will mostly remain on a ballistic trajectory, raining down on what would have been the target.
There's no reason to believe that the radar got destroyed at all. The explosions on the ground were confirmed to be hits on the airport terminal (aftermath pictures are available). Obviously, no part of a Patriot system likely to be inside a building.
Last I heard though, those hits were caused by normal Kalibr cruise missiles. It is a bit concerning that those got through, hopefully they learn from it. But not surprising, because it is challenging for a radar to search for objects both above it and at ground level around it simultaneously.
